mx::sigproc::psdVarMeanParams< _realT > Struct Template Reference

template<typename _realT>
struct mx::sigproc::psdVarMeanParams< _realT >

Parameters for calculating the variance of the mean from a numerical PSD.

Interpolates on the PSD for the integration.

Template Parameters

realT

the real floating point type of the frequency and PSD vectors. [Must be double due to GSL]

psdVal()

template<typename _realT >

realT mx::sigproc::psdVarMeanParams< _realT >::psdVal ( realT  k )

inline

Get the value of the PSD at k using interpolation.

Extrapolates outside the range of frequencies in freq. Right now this is just constant.

Todo:

implement better extrapolation past max-freq.

Parameters

[in]

k

The transformed frequency coordinate
